Which stacking technology supports individual ISL links up to 50G?

• A. VSF
• B. VSX
• C. Both VSF and VSX
• D. Neither VSF nor VSX

Answer: (A)

Inter-switch link (ISL) bandwidth in a stack determines how much data can move between stack members on a single connection. The stacking technology that provides up to 50 Gbps per ISL is VSF, because VSF is designed to treat multiple switches as one virtual chassis and supports high-speed ISLs up to 50 Gbps per link between stack members. VSX uses a different linking method (VSX links) with different per-link speed options (often 40 Gbps or higher on some models) and is not defined by a 50 Gbps per-ISL limit. So the capability to have individual ISLs up to 50G points to VSF.
